New Showmax App not working, terrible client service

Showmax has “updated” or changed the app without informing paid subscribers. The new app isn’t working properly (or not working at all on my side) and none of the complains are acknowledged by them. I see here that they copy and paste a reply to all the bad reviews, but they don’t offer support at all. I’ve inboxed them on Facebook Messenger and they’ve stopped responding and now they just ignore / don’t open my messages. My TV was compatible with the old showmax app and came out with it, now it wants me to download the new app but my tv doesn’t have a playstore. It’s a Hisense Tv. This is absolute bs. The worst part is that they have the audacity to keep on posting adds on social media of how great the new app is while ignoring the hundreds of complaints and comments on those post where it’s clear that none of the paying customers are happy. Super disappointed.
